Wildfire‐Driven Changes in Terrestrial Subsidies Shift Freshwater Microbial and Zooplankton Communities to New Compositional States

Molecular Ecology, EarlyView.
ABSTRACT Wildfire frequency and intensity are increasing globally, impacting terrestrial and aquatic ecosystems. Deposition of burned materials into aquatic environments can affect biotic communities and nutrient cycling. We investigated how post‐fire terrestrial deposition shapes microbial and zooplankton community composition and function across time

Active predators do not necessarily specialize in sedentary prey: A simulation model

Annals of the New York Academy of Sciences, EarlyView.
Active predators, which move to find food, are assumed to specialize in sedentary prey. This study used an individual‐based simulation to test whether this assumption holds. The results show that active predators do not always specialize in sedentary prey; instead, prey choice greatly depends on prey spatial pattern and competition with ambush ...

Selective oviposition of the mayfly Baetis bicaudatus [PDF]

Oecologia, 2006
Selective oviposition can have important consequences for recruitment limitation and population dynamics of organisms with complex life cycles. Temporal and spatial variation in oviposition may be driven by environmental or behavioral constraints. The goals of this study were to: (1) develop an empirical model of the substrate characteristics that best

Do freshwater insect assemblages in exotic plantations resemble those from native forest? Evidence from environmental DNA

Restoration Ecology, EarlyView.
Widespread deforestation has impacted biodiversity patterns globally, but the potential for forest plantations to restore biodiversity remains unclear. Here we used environmental DNA (eDNA) analysis to compare freshwater insect assemblages between native and exotic forests in New Zealand, a region that has experienced heavy deforestation over recent ...

The Good, the Bad, and the Lethal: Gene Expression and Metabolomics Reveal Physiological Mechanisms Underlying Chronic Thermal Effects in Mayfly Larvae (Neocloeon triangulifer)

Frontiers in Ecology and Evolution, 2018
Temperature dictates the performance of aquatic ectotherms. However, the physiological and biochemical processes that drive thermally-mediated life history patterns (and limits) remain poorly understood because they are rarely studied simultaneously.

Optimal Control Strategy for Stability Performance Improvement of Hybrid Power Systems With Electric Vehicle Integration

Energy Science &Engineering, Volume 13, Issue 6, Page 2772-2787, June 2025.
ABSTRACT The present article explores the frequency control of hybrid power systems integrated with electric vehicles (EVs). The hybrid power system is a complicated nonlinear entity that highlights the significant issue of dynamic control owing to inadequate damping under fluctuating load conditions.

Off‐Highway Vehicle Use Degrades a Mountain Stream: A Case Study Evaluating Recreation Impacts, Restoration Efficacy, and Assessing Vulnerability of Headwater Streams in the Central Rocky Mountains

River Research and Applications, Volume 41, Issue 5, Page 1044-1057, June 2025.
ABSTRACT Headwater streams are abundant in mountain landscapes and where municipal watersheds occur on public lands; they co‐occur with road networks open to off‐highway vehicle (OHV) use. Despite well‐known, deleterious interactions of roads and streams, few studies have empirically examined the biophysical impacts of OHV use where backcountry roads ...

Temperature affects acute mayfly responses to elevated salinity: implications for toxicity of road de-icing salts

Philosophical Transactions of the Royal Society of London. Biological Sciences, 2018
Salinity in freshwater ecosystems has increased significantly at numerous locations throughout the world, and this increase often reflects the use or production of salts from road de-icing, mining/oil and gas drilling activities, or agricultural ...

Effects of Benthic Burrows on Hyporheic Exchange

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Macrobenthic invertebrates are widely distributed on sediments, and the micro‐morphology such as burrows and sand mounds due to their bioturbation activities can cause substantial changes in hyporheic exchange (HE). This study explores the characteristics of HE induced by benthic burrows through flume experiments and numerical simulations ...
